MACHINE FOR BLOCKING HORSE-=CQLLARS.

SPECIFICATION forming part of Letters Patent No. 283,878, dated August 28, 1883.

' Application filed February 24, 1883. (No model.)

T0 at whom, it may concern.-

Be it known that I, WASHINGTON FOGLE- SONG, a citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have inventedcertain new and useful Improvements in Collar-Blocking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to collar blocking machines which contain a former, around which the collar is shaped, and which are provided with means for forming the hame-groove.

Heretofore the means for forming the hamegroove consisted, essentially, of a rope, which was drawn around'and tightened on the collar while on the former.

My invention consists, mainly, in the employment of a clamp composed of two curved arms hinged together and adapted to close around the collar while on the former to form the hame-grooves.

It further consists in so organizing the machine that the :t'orm'er may be detached therefrom, together with the collar and the encircling-clamp.

It further consists of certain other combinations,which will be stated in the claims at the close of this specification.

In order that my invention may be clearly understood, I have illustrated in the annexed drawings, and will proceed to describe, the best form of my invention at present known to me.

Figure 1 is a perspective view of my improved collar-blocking machine. Fig. 2 is a section on the line S T of Fig. 3, which is a plan view of the former, clamp, and part of the means for operatingthe clamp. Fig. 4 is a vertical section on the line Y Z of Fig. 3, also showing the table for supporting the former.

The same letters of reference indicate identical parts in all the figures.

The former A rests with its base on the table 5 of a suitable bench or frame, B. At one end the base of the former abuts against the base of a goose-necked standard, 0, while its other end fits under guides b, and at one side the base of the former is provided with a downwardly projecting lip, a, which brings up against the edge of the table I) and insures the proper position of the former with reference to the other parts of the machine. formerlis slid laterally upon the table,and cannot move endwise while in position thereon.

The clamp consists of two stiff curved arms, D D, hinged together at one end, and so shaped that when closed they will include a space somewhat larger than the area of the former, but having substantially the same contour, as clearly shown in Fig. 3. In order that the arms of the clamp may present a continuous surface along that portion of the hinge-joint which acts on the collar, the hinged ends of i The the arms are constructed with wings d d, and

the pivots inserted in these wings, so that their axis will beccoincident with the inner side of the adjacent central ends of the arms between the wings, as shown in Figs. 1 and 3. Near the center of each arm ears are formed for the attachment of links E E, pivoted at their outer ends to the extremities ofthe reciprocating fork F, the shank of which is secured to cross-bars F F, fitted to slide on guide-rods G G, mounted on the bench of the machine. A rack is formed on the under side of the shank of the fork F, engaged by a pinion, H, on the cross-shaft I, which is provided. with a suitable winch for turning it to reciprocate the fork. The free end of one of the arms of the clamp is provided with a laterally-projecting bar or stud adapted to enter the slot in the other arm, in order that the two arms of the clamp may be secured together in a closed position by passing a pin through the projecting end of said bar or stud, as shown in Figs. 1 and 3, thus holding the clamp firmly to the collar when the clamp is released from the action of the reciprocating fork.

A vertically sliding presser bar, K, is mounted on the head of the goose-neck O. The extreme ends of the presser-bar are constructed with downwardlyprojecting feet,

adapted to press on the top of the respective The presser-bar is connected with a screw, L, by means of which it can be raised and lowered when required. I

The machine is operated in the following manner: A reciprocating fork having been drawn back, a suitable former is slid in posi tion on the table of the machine, and a clamp corresponding to said former is connected to the links E E of the reciprocating fork. A collar is then placed on the former and the fork F moved toward the former, carrying with it the clamp, which comes first in contact with the collar at about the hinge-joint, and being then prevented from moving onward with the fork, its arms are gradually closed upon the collar until, at the extreme end of the forward stroke of the fork, the bar or stud on one arm of the clamp has passed through the slot in the other arm so far as to admit of the two arms .being screwed together, in the manner hereinbefore set forth. The presser-bar is then forced down upon the screw L for the purpose of shaping therim of the collar. That having been accomplished, the presserbar is run up, the links E E disconnected from the former of the clamp, and the fork "run back. The former, together with the colclamped on the formers, may be kiln-dried in machine may be continuously operated upon, 3 5 the collars held clamped to the formers for a sufficient length of time to set.

The formers and clamps may be made of metal, in order that the collars, while still a suitable kiln.

Having thus described my invention, what I claim is 1. In a machine for shaping previouslystuffed horse-collars,the combination, substantially as before set forth, of the former and the clamp, provided with means, substantially as described, for operating'the same.

2. In a machine for shaping previouslystuffed horse-collars, the combination, substantially as before set forth, of the former, the clamp, and the reciprocating fork for moving and closing the clamp.

' 3. The combination, substantially as before set forth, of the former, the clamp, and the presser-bar.

4. The clamp composed of two stiff curved arms, hinged together by wings on an axial line coincident with the inner side'of the adjacent ends of the arms, in combination with the former, substantially as before set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WASHINGTON FOGLESONG.
